Soup takes Reverator’s in-camera grain plate and simulates the development of the photographic emulsion through the traditional film processing chain. In addition, Soup emulates looks associated with outcomes of irregular film processing, primarily through user control of the develop cycle (developer, agitation, replenisher), silver retention, and contrast diffusion across a tunable range of spectral densities.

By default, Soup capitalizes on traits associated with reduced film agitation, namely : tempered highlights, reduced global contrast, increased local contrast, dense color purity particularly in dark regions, and a greater concentration of fine-grained tonality. To compliment Soup’s lab related controls (silver halide sensitivity, pull | push processing, developer concentration, agitation, replenisher, spectra diffusion, bleach bypass, printer lights), Soup provides soft clips, shadows, midtones, highlights, offset, and gamma. Gamma was not used in any of the examples shown on this page.

Film developer works and depletes quicker in bright areas than in dark areas. Agitation tempers the effects of this phenomenon by controlling the flow of fresh developer (replenisher) into the bath. Lower replenisher rates (lower agitation periods) allows active developer to remain longer in dark areas where the least sensitized salt crystals require the most time to fully develop. A single agitation period in the middle of the develop cycle has the exhausted developer resting undisturbed in the highlights (acting as a buffer from further developing), while allowing active developer to continue building density in the shadows. By giving the developer more time to work in the shadows, it brings out more details than otherwise would be possible through multiple agitations.

Each agitation period in a develop cycle dispenses some fresh developer. With fewer bright areas remaining undeveloped, and denying dark areas the time to fully develop, developer solution depletes at a slower rate over the develop cycle. Manually reducing replenisher allows existing active developer time to work in dark areas, while restraining developer in bright areas. However, with very little or no agitation, manually reducing replenisher has the effect of lowering developer concentrate, limiting its ability to expose salt crystals in both light and dark areas.

Soup extends capabilities beyond traditional film processing through Spectra. Through the scattered diffusion of undulating film densities, Spectra’s tunable frequency bands can induce dreamy to dramatic film looks. Spectra rides on retained – yet active – developer, and is particularly effective when restricting replenisher flow.

As emulsions contain grains of varying sizes, push processing increases the exposure by placing more density in the least sensitized finer-grained layers. This tends to decrease overall  graininess, but pushing too far increases contrast and may curtail fine details in highlights. Push processing also strengthens color saturation. Limited agitation brings significant speed (sensitivity to light) increases to film, allowing for aggressive push processing with manageable contrast buildup.

An increase in agitation lessens the buffering effect of exhausted developer in brighter regions as fresh developer is dispersed multiple times through the develop cycle. As the developer is selective (favoring highlights), increased agitation prevents the developer from exhausting in the shadows that would otherwise compensate for an increase in global scene contrast.

There are several ways to compensate for over-developed highlights, increased contrast, and density build up from higher agitation periods. Typically, developer concentration dilution restricts contrast, and a pull process lowers densities. To boost shadow details, lower the agitation period and the replenisher level. This tempers overall contrast, and provides expected grains correlation with push processing (where many of the formally under-exposed grains in the shadows become developable and convert to silver).

Used in combination (Silver salt sensitivity, Pull | Push, Developer, Agitation, Replenisher, Spectra, Diffuse), each lab process contributes to different outcomes. As the replenisher is calibrated with each agitation period, there is no loss of film speed when the replenisher is kept at its default setting.

 

ACES AP0 Soup. Bleach bypass preset. User customizable. Boost mode

Bleach bypass typically works best in low-contrast and highly saturated scenes. Fixing agents in a bleach bath dissolve unexposed and undeveloped silver halide crystals from the layers.  Metallic silver is already desensitized, but unexposed crystals are still light-sensitive and need to be neutralized. Reducing or skipping this bath retains some or all the silver. And just like developer solution, given enough time, the fixer will attack and dissolve all metallic silver. Any retained silver through bleach bypass increases the contrast and grain, while fewer dyes render a restricted color palette of lower saturation. There can be a significant reduction in dynamic range, making it difficult to recover details in the shadows. There can be  color shifts, usually towards cyan, and maroons and blues tend towards black.
